Versuchsvorschrift

The required β-methylaminoethyltriphenylphosphonium bromide was prepared by heating a mixture of β-phenoxyethyltriphenyl phosphonium-bromide (46.2 g.) dissolved in ethanol (80 ml.) and 33% ethanolic methylamine (130 ml.) in an autoclave at 100° C for 3 hours. After cooling, the produce was precipitated by addition of dry ether (2 l.) filtered, washed with ether and dried, and had a melting point of 226° C.
